Description
Technical field
The utility model belongs to technical field of automobile parts, relates to a kind of automobile driving axle.
Background technology
In order to make the automobile power transmission, all can use automobile driving axle, adopting maximum at present is the ball cage type axle drive shaft, has all solved constant speed transmission problem preferably no matter this kind axle drive shaft is circular arc alley or liner ball road, and it is big to transmit operating angle, efficient is high.Automobile on the way goes; The situation of running into is quite complicated, and present drive shaft assembly has just been done some variations on driving angle, and operating angle is little; Ball cage assembly comes off easily; Can not adapt to complicated pavement state, and load-carrying capacity is also relatively poor, therefore is necessary existing automobile driving axle assembly is improved.
Summary of the invention
The utility model technical matters to be solved is the present situation to prior art, and provides a kind of simple in structure, and load-carrying capacity is strong, guarantees the automobile driving axle of operation stability.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of automobile driving axle, comprise internal spherical cage, ectosphere cage, input shaft, output shaft and tween drive shaft, and described internal spherical cage and ectosphere cage interconnect through tween drive shaft; Output shaft is connected on the ectosphere cage, it is characterized in that, described internal spherical cage comprises housing, ball cage assembly and dustproof body; Described ball cage assembly is arranged in the housing; Described input shaft comprises bearing end and coupling end, has spline in last bearing end, and input shaft is connected on the housing through coupling end; Edge between coupling end and housing is equipped with back-up ring, between bearing end and the coupling end seal ring is installed.
The measure of taking for the optimization such scheme specifically comprises:
In above-mentioned a kind of automobile driving axle, on the described ectosphere cage braking gear ring is set also.The braking gear ring can be strengthened the control to car, when emergency braking, can keep operability significantly, has reduced hydro-planing, has shortened stopping distance effectively.
In above-mentioned a kind of automobile driving axle, also be provided with spline on the described output shaft, connector and lock nut are installed on the end of output shaft.
In above-mentioned a kind of automobile driving axle, described dustproof body one end is connected on the tween drive shaft, and the other end is connected on the outer wall of housing, between dustproof body and tween drive shaft, housing, is provided with clip.Here can guarantee that through clip dustproof body has certain elastic deformation space, can increase the elastic force between dustproof body and the tween drive shaft again relatively.
Compared with prior art, the advantage of the utility model is to change operating angle arbitrarily, changes under the situation greatly in driving angle; Also can keep certain working stability, can adapt to complicated pavement state, and the constant speed transmission be effective; Spline has improved load-carrying capacity, and back-up ring reduces the wearing and tearing to housing, has improved service life; The braking gear ring has reduced hydro-planing, has shortened stopping distance effectively.
